The Celestron Focus Motor enables electronic focusing using a computer or Celestron computerized mount hand controller for remote hands-free observing.
The Focus Motor provides electronic focusing for Celestron Schmidt-Cassegrain (SCT), EdgeHD, and RASA telescope optical tubes.
With the focus motor installed, you can bring celestial objects into sharp, precise focus using your telescope’s hand controller or a computer instead of using the focuser knob.
A focus motor is great for visual observers who want to dial in exact focus (especially those with dexterity issues) and a must-have accessory for astroimagers. With a motorized focuser installed, an astroimager no longer needs to be physically near the telescope to focus an image. Combined with computerized control of the mount and camera, the focus motor enables the imager to gather data remotely from a backyard observatory, or even a telescope located hundreds of miles away. As an added bonus, port covers protect the ports while not in use, and the covers cannot be lost due to the tethered design.
Compatible Optical Tubes
For 6” Schmidt-Cassegrain telescopes only, the Off-Axis Guider (#93648) cannot be used when the focus motor is installed due to mechanical interferences.
There are three options for powering your Celestron Focus Motor:
To use third-party focuser control software, an ASCOM driver is needed.
